A friend has a good body and is using the CL casual encounters section. However, he tells me that he gets good responses but the problem is when he responds and posts a pic the girls stop responsding

He gave me examples:

EX 1

Her: Still looking? He: Yes, still looking (and posts a pic)

Conversation ends

EX2:

Her: Hey whats up? (name) here. Where are you located? what are your stats? Disease free? Single? What did you have in mind for extremely naughty adventures. Im pretty much down for anything. He: Hey (name) here. I am located in (location). Disease free and single. I can host anytime today and tommorow. Any fetishes?

conversation ends

So, I was wondering how casual encounters work and what would be the normal sequence of conversation and events. Maybe I can help my friend and try it myself
